Ithe oil is disclosed by the upward passage of the oil-drops through a body of water contained in a glass or other transparent receiver; and it consists in the construction and arrangement ofthe several parts of the lubricator, as hereinafter described.

In the accompanying drawings, Figure 1 is a vertical central section ot' a lubricator embodying my improvement. A-

A is a metallic oil-receiving chamber, carry ing on one side an external glass gage, B, opening at the top into the interior of the chamber, and at the bottom into the waste-passage a ot' the plug C, which is also provided with a branch passage, b, in communication with a discharge-passage, b', leading from the bottom ofthe chamber A. The glass tube which con stitutes this gage has a packing at each end,

and is pressed up into its upper bearing and held tightly in place with sealed joints by means of plug C, which screws into a bearing up against the lower end of the gage-tube, as shown plainly in the figure. The dischargepassage a is controlled by a waste-cock, c. The lateral extension from the oil-chamber, in which the upper end of the gage is seated, is prolonged in an upward direction to form a bearing, D, int-o which the lower end of the vertical tube E is screwed. The oil is supplied to the chamber A through the upper end ot' this tube, which is closed, as shown, by a packed removable cap, F. The tube E thus becomes virtually an extension ot' the oilchamber A, and is intended to receive within it the oil-feed tube Gr. The upper end of this tube is located in the upper portion of the said vertical extension. The oil-feed tube thence extends downward into the body ot' the oilchamber, and Ihence extends upward, so as to project throng and a little above the head of saidchamber and into the lower portionof the l glass dome H, which is secured in place on top of the oil-chamber by means of a nut, I,

which surrounds it and screws into a bearing,

J, ou the oil-chamber.

'The end G of the oil-feed tube constitutes a nozzle from which the oil is discharged, and passes up through the body of water with which the glass dome is to be partly tllerl.

From the upper portion of the glass dome extends the oil-discharge tube K down through the oil-chamber A, and into a passage, d, in the plug` L, which is screwed into the bottom ofthe oil-chamber. The drops of oil discharged from the nozzle G gather upon the surface of the water in the glass dome, and thence pass over into the upper end ot' the oil-discharge tube K, through which tube and the pipe or pipes connected with the lower end of the same the oil is conducted to the parts to be lubricated.

By reason of the extension 13,1 am enabled,

passage d, is provided with a passage, e, for

the entrance of the water, which raises the body of the oil in the oil-chamber into the extension E high enough to cause it to pass over into the oil-feed tube. The plug is also provided with two tubular branches, L L2, communicating one with the passage e and the other with the passage d, each being controlled by a separate valve, e' andv d. The branch L receives the pipe M, which supplies the water that operates, by its pressure, upon the oil in the oil-chamber, substantially as described in my Letters Patent No. 11,958, of November 21, 1854. The other branch, L2, receives the pipe N, which conveys the oil to the parts to be lubricated. y

A modification of my improvementis shown in Fig. 2, which is a vertical central section of a lubricating apparatus. In this apparatus the oil-feed tube G, while still having the point at which the oil begins to descend through it to its dischargenozzle abovethe point at which IOO 2 p 23ans the oil in the glass dome passes over into the oil-discharge tube K, is so arranged as to be contained Within the glass dome, thus dispensing,` with the vertical extension E of Fig. 1. I accomplish this result by extending the oil-feed tube Gfrom the top ofthe oil-chamber up into the upper part of the dome, so as to carry it above the upper end of the oil-discharge tube K; thence down to near the bottom ofthe glass dome, and thence upward a short distance, so that it may have au upwardly-tnrlied discharge-nozzle, G.

In the apparatus shown in Fig. 2, I dispense with the glass gage, and I put the waste-passage in the plug L between the passages @and d, as indicated atf. lith this exception the apparatus shown in Fig. 2 is constructed iu the same way as the apparatus shown in Fig. l.

By having,` that part of the tube G from which the'oil descends to the discharge-nozzle elevated above the upper end of tube K, I am enabled to readily till the glass dome With u'ater through tube G, aud then draw off the Water from the cup or chamber A Without aecting` that in the dome above. The plug or shank L, constructed with the three separate independently, valve-controlled passages, as shown in Fig. 2, affords a convenient and ready means oi" connecting' all the va'rious parts of the apparatus.

Having thus described my improvements, what I claim, and desire to secure by'Letters Patent, is-

rlhe oil-chamber A, provided with plug L and separate passages for entrance and escape ot' Water, andthe glass dome H, mounted upon and secured to the top ot' the oil-chamber, in combination with the oil-disch arge tube K, extending from the upper part of the glass dome down through the oil-chamber, and the bent oil-feed tube G, having that part from which the oil descends to the discharge-nozzle elevated above the upper end of discharge-tube K, as herein shown and described.

In testimony whereof I have hereunto set my hand this 30th day ot' December, 1881).
